Wash the rice and glutinous rice until the water runs clear.
Put rice, carrot and dried shrimps in the pot, fill generously with water, approx 1 part rice to 3 parts of water.
Let simmer for about 40 minutes, check every 15 minutes and scrape the bottom to make sure rice doesn’t stick to the bottom. Add in water if the porridge becomes too thick.
When the porridge is about to reach the desired consistency (half of the grain will lose its shape and the mixture has a milky color), start seasoning to taste. Add in the spring onion bulb and century egg. Continue simmering for 3 minutes and turn off the heat.
Serve hot, sprinkle with pepper, spring onion, coriander and dried shallots.
